Okay, let me go over what happened. I'm borrowing my girlfriend's macbook because the video card on my Windows desktop died. I am currently enjoying 648x480 res & 4bit color as I write this post. My girlfriend and I decided to go out for the day, and we decided to let my little brother use the laptop while we were gone. SO APPARENTLY, he decides he wants to install photoshop. It prompts him for an admin password, which I didn't leave with him. He can't get in touch with me because I'm in a movie with my phone off. This is where it gets bad. What he told me he did is listed here: Hack 2 Fooling OS X with Registration Process : Reboot Hold apple + s down after you hear the chime. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line): mount -uw / rm /var/db/.AppleSetupDone shutdown -h now After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and youre good to go again! taken from: http://www.ihackintosh.com/2009/05/how-to-hack-the-user-password-in-mac-os-x-without-an-os-x-cd/ What happens now is, when it boots, the grey screen with the logo appears along with a progress bar. The progress bar updates to about 1/10th of the way, freezes and disappears. Then the spinning wheel just sits and spins indefinitely. fsck -fy comes back with a keys out of order error -- trying to fix them results in disk0s2 i o error. Booting verbose mode generally seems to loop that, too. We do not currently have the install disks but I could have them mailed to us. I'm 99% sure it's not hardware-related. The drive was purchased under a year ago and has been tested periodically. This never happened until he did what he did. Any idea what I can do?
